it 'may concern: g

Be it known that I PEMBROKE D. HARTON, a citizen of the United States,residing -ini Pennsylvania, have invented? certain Improvements inCake-Coating Machines, of which the following is tion.

The object of 'my invention is to provide a specificacoating biscuits,lcakes and" other similar; baked articles bf relatively small size, withi icing or with other similar matenal such as lchocolate, marshmallow orthe like.

The apparatus'forming the subject of my invention is so constructed thatthere is no l handling'of the cakes from the time -they are entered intoa Suitable delivery hopper until they are removed from the carrier readyfor My invention is fully shown in theaccomlgure 1, is a side elevationlof a machine embodying my invention; Fig. 2, is a sectional view on theline (Lea, Fig. 1; Fig. 3, is. a sectional vieuT on the line b-b, Fig. 1Fig. 4, is a sectional'v view on the line @50, Fig. 1; Fig. 5, is aperspective view of a detail of my invention; '#Fig 6, is an enlargedView of part of the mechanism'shown in Fig. 1, and Figs. 7*. and 8,areviews illustrating modified dei g The machine forming thesubj ect ofmy ina coating belt 2, which is traversed by suith able mechanism, andbelow said belt a traveling conveyer belt 3 upon which suitablereceptacles 4 may be placed. The belt 2 is designed to receive coatingmaterial such as icing, chocolate, etc.,which is indicated at 5, andthis coating is distributed to the belt from a reservoir 6suitably'mounted, beneath which said belt passes. In front ofsaidresseries of hoppers, 7, for cakes, biscuits and the like, and from thebottom of said hopper or hoppers a delivery chute 8 extends whereby thecakes may bel delivered onto the coatedbelt 2.

To deliver cakes from the hopper or hoppers, I provide a roll 9 havingradial pins 10 disposed throughout its length to engage said cakes; theroll being driven at a convenient rate of speed whereby the engagementof the i lsame.

pms wil serve to carry from the hopper or hoppers the lowermost cakeswithin the same.

The hoppers are removable so that different sizes may be employedand'their bottoms are slotted so as to permit movement of the pins pastthe same. The cakes pass over a slight fr rise 11 at the lower endof thedelivery chute ,i

8 whereby they may be dropped evenly onto the coating carried by thebelt 2. As the cakes are carried forward b v the belt they are engagedby a pressure roll 12 lto insure proper and sufficient contact with thecoating material and after leaving said pressure roll they are carriedto a point for removal from said belt 2 and delivery to a suitableconveyer belt, suchas indicated at 3. ln order to discharge the cakesfrom the belt 2, the latter is given a sharp turn around a small bar 13,which is adjustably mounted, as clearly shown in Fig. 5, and as saidcakes tend to pass beyond the edge formed by the sharp turn, they areengaged by pins 14 carried by a roller 15 journaled in suitable bearings16 and driven in such relation to the belt 2 as to properly engage thecakes delivered by the same, The bar 13 is carried by arms 17 journaledin bearings 18, and threaded stems 19 carried by the frame 1 passthrough slotted lugs 20 on said arms. said stems lie between the lugsand by turning these nuts the arms may be adjusted np and down.

The cakes removed from the belt 2 by the means just described aredelivered to an adj ustable delivery chute 22 from which they aredropped onto boards or other receptacles 4 mounted on the conveyer belt3 and from thence said cakes are delivered tosuitable cooling chambersto set the coating upon the As the coated belt 2 will carry a certainexcess of material I provide below the lowerniost-run of said belt adrip trough 24 into which said coating material may'lall and said driptrough delivers to a drip box 25.

The pressure roller 12 is loosely mounted on its driving shaft 26 andsince the Alatter i.l driven at a relatively high speed this roller willbe givensulicient rotative movement to cause it'to ride over thesuccessive cakes, ,thereby pressing them into the coating on the beltwithout crushing their edges. The machine is provided with a suitabledriving shaft 27 having a pulley 28 b vwhich it is driven. Said shaftalso carries a chain wheel 29, and a chain 3() extends iroml the same toa chain wheelSl o n a shaft 32 for driving the coating belt 2, and to achain Nuts 21 adapted to` wheel 33 on a shaft 34 which is geared to ashaft 35 .vhereby the conveyer belt 3 may be driven. 'lhe roll 9 isdriven by a belt 36 from the shaft 32; the shaft 26 is driven by a belt37 from the roll 9, and the shaft 16 isdriven by a belt 3S from theshalt 26. By the use of such driving mechanism, the several parts" maybe operated and the belts driven al' proper relative speeds for thecarriage of the several cakes in the coated and uncoated` conditionthrough said machine.

Although l. have shown certain means for delivering the cakes to and'l'rom the coating belt and to and from the conveyor belt, l do not wishto be limited to any particular mechanism foraccomplishing theseobjects, l may use a toothed wheel 40, as shown in Fig. 7, oraknife-edged wheel 41, as shown in Fig. 8, for this purpose.

I claim:

l. The combination ot a coated belt, means for delivering calves ontosaid belt, and rotating pickers for removing said cakes therefrom.

The combination ol a coated belt, a cake reservoir, a chute leading fromsaid reservoir, means for delivering the cakes in said reservoir to thechute Afor passage to the belt, and rotating pickers for removing thecoated cakes from said belt.

3. The combination of a coated belt, means for delivering cakes thereto,rotating means for pressing said cakes into the coat-` ing material, androtating pickers for removing the cakes from said belt. j

4. The combination of a coated belt, means for delivering cakes thereto,a second belt, and rotating pickers for removing the cakes from thei'irst belt and delivering them to the second belt.

5. The combination of a movable coated carrier, means for deliveringcakes thereto, and rotating pickers for removing said cakes from the coated carrier.
